HEATING DEVICE FOR WATER-JACKETED CARBURETERS.

Specification of Letters Patent. I

Patented Feb. 20, 1917.

Application filed June 1, 1916. Serial No; 101,184.

To all whom it may concern:

Be it known that I, RoY A. F IsK, a citizen of the United States,residing at Amboy,

1n the county of Blue Earth, State of Minnesota, have invented certainnew and useful Improvements in Heating Devices for Water-JacketedCarbureters; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to .which it appertains to make and use the same.

This invention relates to carburetors and has special reference to aheating water acketed carbureters.

ne important object of the invention is to provide means whereby thewater of a water jacketed carbureter may be heated, the means being ofimproved character so that the hydro-carbon in the carbureter will bevaporized and the entering air warmed whereby the compression will begreater, the engine will fire quicker, and consequently there will beproduced a greater mileage to the given quantity of the hydro-carbon.

A second important object of the invention is to provide a device ofthis description wherein the water in the water jacket will be kept inproper circulation during the operation of the engine.

With the above and other objects in view, as will be hereinafterapparent the invention consists in general of certain novel de-- tailsof construction and combinations of parts hereinafter fully described,illustrated in the accompanying drawing, and specifically claimed.

In the accompanying drawing, like characters of reference indicate likeparts in the several views, and

Figure 1 is a side elevation of a carbureter with the water jacket andother connected parts shown in section;

Fig. 2 is a plan view thereof;

Fig. 3 is a section on the line 3-3 of Fig. 2, the carbureter bodyproper being shown in elevation.

In the present embodiment of the invention, the invention has been shownas aplied to the carbureter which is commonly known as a Rayfieldcarburetor and the body of such a carburetor is indicated at 10.Surrounding this body 10 is a wall 11 so device for that between thebody and the wall is formed a water jacket 13. At 14 is a cylindricalreceptacle which constitutes a water'heat'ing chamber and the upper cleis closed by a plug 15 supporting an,insulating sleeve 16 through whichpasses the electric wires 17 the wires being preferably connected to astorage battery of suitable voltage. Depending from the plug 15 is theheating element which consists of a tube l8- closed at its bottom andcarrying within it a resistance coil 19. The lower end of thisreceptacle 14 is connected to the bottom of the water jacket by means ofa passage 20 while the upper end of the water jacket is connected to theupper part of the receptacle 14 by a tubular connection 21. Theconnection 20 has depending therefrom a petcock 22 for the purpose ofdrawing off the contents of the water jacket and receptacle 14 whendesired and also the water jacket is provided with an overflow pet-cock23.

At 24 is a filling tube which is connected to the water jacket by a bend25 and which is normally closed by a plug 26. This filling tube isprovided with an overflow valve 27 at one side.

In the operation of the device, when it is desired to start thecarbureter the water jacket is preferably filled with hot water. Then,the carbureter may be started readily with the hydro-carbon vaporizedproperly. After being started, the current is turned on the wires 17 bymeans of a switch located on the dash of an automobile and the water inthe receptacle 14 heated. As the water is heated, there is established acirculation upwardly of the receptacle 14 and thence through theconnection 21 to the body of the water jacket 13. This action willultimately heat the entire body of water in the jacket 13 by reason ofthe cross currents that will naturally be established under theinfluence of the discharge into the body 13 through the passage 21 andthe oppositely directed flow through the connection 20.

There has thus been provided a simple and elficient device-of the kinddescribed and for the purpose specified.

It is obvious that many minor changes may be made in the form andconstruction of the invention without departing from the materialprinciples thereof. It is not therefore desiredto confine the inventionto the exact form herein shown and described but it is wished to includeall such as properly come within the scope-claimed. I

end of this recepta-" ment in the heating chamber and ber having itslowen'end connected to the a heating chamlower end of the water jacket,a heating element in the heating chamber consisting of a tube extendinginto the chamber and having a closed lower end, and a resistance coil insaid tube, and a tubular connection between the upper parts of the waterjacket and heating chamber;

In testimony whereof, I afiix my signature, in the presence of twowitnesses.
